Mae Conway, a resident of Oakland Heights affordable-housing apartments in Kansas City, Missouri, had struggled with poor respiratory health for years. She used an oxygen tank, a breathing machine, and a sleep apnea machine, all of which require a lot of electricity. Over the years, Oakland Heights had fallen into disrepair and had become increasingly energy inefficient. “I live on a fixed income,” says Conway. “When the rooms were drafty and my heating and cooling bills were high, I worried that I couldn’t keep my machines running.” Conway used to keep the lights and television turned off so she could afford to pay for the electricity she needed to treat her respiratory problems.
